FIG. 1 illustrates a block diagram of an electronic device according to an embodiment of the inventive concepts.

Electronic device 1000 may store data, may manage the stored data, and may provide necessary information to a user. According to an embodiment, the electronic device 1000 may be a device included in an infotainment system for a vehicle. For example, the vehicle may be an automobile, but is not limited thereto and may be other types of vehicles. The electronic device 1000 may be for example a navigation device or a media content player. For example, the electronic device 1000 may be a device for advanced driver assistance systems (ADAS). According to another embodiment, the electronic device 1000 may be a personal computer, or a mobile electronic device such as, but not limited to, a notebook computer, a mobile phone, personal digital assistant (PDA), a camera or the like.

The electronic device 1000 as shown in FIG. 1 includes host 1200 and storage device 1400. The electronic device may include additional circuitry and/or components not shown.

The host 1200 may provide various services to the user of the host 1200 as one or more electronic circuits/chips/devices operate. The host 1200 according to an embodiment may perform various operations for the purpose of processing commands received from the user of the host 1200 and may provide the operation results to the user of the host 1200. The host 1200 according to an embodiment may include an operating system(s), an application(s), and the like. The host 1200 according to an embodiment may include an operation processor(s) (e.g., a central processing unit (CPU), a graphic processing unit (GPU), an application processor (AP), and the like) including dedicated logic circuits (e.g., field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), and the like).

The storage device 1400 may store data. According to an embodiment, the storage device 1400 may be for example an embedded multimedia card (eMMC), universal flash storage (UFS), a solid state drive (SSD) or the like.

The storage device 1400 may be installed in a vehicle. In this case, the storage device 1400 may store various data necessary for vehicle driving. According to an embodiment, the storage device 1400 may for example store data associated with media content, map data, and data (e.g., sensor data) associated with the safety of a vehicle. The storage device 1400 may include a nonvolatile memory for storing data. For example, the storage device 1400 may include a plurality of flash memories.

To request the storage device 1400 to perform various operations, the host 1200 may transmit various commands (i.e., Command in FIG. 1) to the storage device 1400. A data-associated command that the storage device 1400 receives from the host 1200 may include, but is not limited to, a read, write, or erase command for data. The storage device 1400 may perform a read operation, a write operation or an erase operation associated with data stored or to be stored in the storage device 1400 responsive to a command from the host 1200.

A command that is transmitted from the host 1200 to the storage device 1400 may be received by a controller (not illustrated) of the storage device 1400. The controller may perform an operation corresponding to a received request, and may return (send) a response (hereinafter referred to as a “command response”) to the received command to the host 1200. The command response (i.e., Response to command in FIG. 1) returned to the host 1200 may indicate the result of processing the received command. For example, the command response to the received command may include information about whether the received command is successfully processed.

The host 1200 according to an embodiment may transmit a read command (e.g., a get or read command) associated with data to the storage device 1400, and the storage device 1400 may process the received read command and may return the command response to the host 1200.

The host 1200 according to an embodiment may transmit a write command (e.g., a put or write command) associated with data to the storage device 1400, and the storage device 1400 may process the received write command and may return the command response to the host 1200.

The host 1200 according to an embodiment may transmit a delete command (e.g., a delete, unmap, or erase command) associated with data to the storage device 1400, and the storage device 1400 may process the received delete command and may return the command response to the host 1200.

The storage device 1400 may transmit temperature information to the host 1200 by additionally including temperature information in the command response to be returned to the host 1200. When a temperature of the storage device 1400 is out of a reference temperature range, an operation of the storage device 1400 or the reliability of data cannot be secured. The storage device 1400 may prevent an unexpected error capable of occurring, by transmitting its own temperature information to the host 1200 in advance.

The temperature information may be information about an internal temperature of the storage device 1400. The internal temperature of the storage device 1400 may be different from a temperature of air around the storage device 1400 or a temperature of the exterior of the storage device 1400. For example, the internal temperature of the storage device 1400 may mean a temperature of a non-volatile memory device within the storage device 1400.

The temperature information according to an embodiment may include information about whether the internal temperature of the storage device 1400 is out of a reference temperature range. For example, the temperature information may include information about whether an internal temperature measured by a sensor included in the storage device 1400 is lower than a lower limit reference temperature (e.g., a second reference temperature) and/or information about whether the internal temperature measured by the sensor is higher than an upper limit reference temperature (e.g., a first reference temperature).

The reference temperature range means a temperature range where the storage device 1400 operates stably and normally without causing an error (or without an abnormal operation). The reference temperature range according to an embodiment may for example be determined in compliance with the AEC (Automotive Electronics Council) standard being the semiconductor reliability test standard for a vehicle. For example, according to the AEC standard Grade 3, the reference temperature range may be determined to be −40° C. to 85° C.

The temperature information may be included in the command response to be transmitted from the storage device 1400 to the host 1200. For example, the storage device 1400 may process a write command received from the host 1200 and may return, to the host 1200, the command response indicating the result of processing the write command. In this case, the storage device 1400 may record (i.e., include) the temperature information in the command response. For example, in the case where the command response transmitted to the host 1200 is in the form of a bit string, information about whether the internal temperature of the storage device 1400 is lower than the lower limit reference temperature and information about whether the internal temperature of the storage device 1400 is higher than the upper limit reference temperature may be respectively expressed by using bit values.

The host 1200 may perform a thermal throttling operation for controlling the internal temperature of the storage device 1400, based on the temperature information received from the storage device 1400. For example, when the internal temperature of the storage device 1400 is determined to be out of the reference temperature range, the host 1200 may perform various control operations for adjusting the internal temperature of the storage device 1400. The thermal throttling operation will be more fully described later.

FIG. 2 illustrates a block diagram of an electronic device according to an embodiment of the inventive concepts.

An electronic device 2000 of FIG. 2 is a detailed embodiment of the electronic device 1000 of FIG. 1. Accordingly, the description given with reference to the electronic device 1000 of FIG. 1 may also be applied to the electronic device 2000 of FIG. 2. For example, a host 2200 and a storage device 2400 of FIG. 2 may correspond to the host 1200 and the storage device 1400 of FIG. 1, respectively.

The storage device 2400 includes a memory device (memory) 2600 and a controller 2800.

The memory device 2600 may include a non-volatile memory for storing data. For example, the memory device 2600 may include a plurality of flash memories. Alternatively, the memory device 2600 may include other kinds of non-volatile memories such as phase-change RAM (PRAM), ferrroelectric RAM (FRAM), and magnetoresistive RAM (MRAM) or the like.

The controller 2800 may receive a command associated with data from the host 2200 and may perform various operations in response to the received command. The controller 2800 may process a command and may return, to the host 2200, a command response 2900 indicating the result of processing the command.

The controller 2800 may control overall operations of the storage device 2400. For example, the controller 2800 may schedule operations of the memory device 2600 or may encode and decode signals/data to be processed in the storage device 2400. For example, the controller 2800 may control the memory device 2600 to allow the memory device 2600 to store or output data.

The controller 2800 may be connected with the memory device 2600 through a plurality of channels (not illustrated). The controller 2800 may include hardware or software devices (not illustrated) for performing operations in response to various requests from the host 2200. The controller 2800 according to an embodiment may include volatile memory (not illustrated) such as dynamic random access memory (DRAM), static random access memory (SRAM), or synchronous DRAM (SDRAM), or the like.

The controller 2800 may include one or more hardware components (e.g., an analog circuit, a logic circuit, and the like) that are configured to perform functions described above and to be described below. Additionally or alternatively, the controller 2800 may include one or more processor cores. Functions of the controller 2800 described above and to be described below may be implemented with program code of software and/or firmware, and the processor core(s) of the controller 2800 may execute an instruction set of the program code. The processor core(s) of the controller 2800 may process various kinds of arithmetic operations and/or logical operations for the purpose of executing the instruction set.

The controller 2800 may include a sensor 2820 for measuring an internal temperature of the storage device 2400. For example, a thermoelectromotive force (or thermocouple) sensor using an electromotive force that varies with temperature, a thermal conductivity sensor sensing a value of a resistor that varies with temperature, and the like may be used as the sensor 2820. However, the inventive concepts are not limited thereto, and other types of temperature sensors may be used. The sensor 2820 may be configured to measure a temperature of a junction portion of the controller 2800 and the memory device 2600, and the measured temperature may be determined as an internal temperature of the storage device 2400. The sensor 2820 may measure a temperature at a junction portion between the controller 2800 and the memory device 2600.

Referring to FIG. 3, “T_(Case)” indicates a temperature of a case of the storage device 2400, and “T_(Ambient)” indicates a temperature of ambient air of (i.e., surrounding) the storage device 2400. The sensor 2820 may measure a temperature T_(Junction) of a junction portion 3300 of the controller 2800 and the memory device 2600. “T_(Junction)” may be determined as an internal temperature of the storage device 2400. However, the manner in which the sensor 2820 measures the internal temperature of the storage device 2400 is not limited as here described.

Returning to FIG. 2, the controller 2800 may include registers 2840 (e.g., Reg#1, Reg#2, . . . Reg#n) for accelerating an operation. At least a part of the registers 2840 may be used to manage the reference temperature range to be applied to the storage device 2400. For example, at least one of the registers 2840 may be used to manage a value of the upper limit reference temperature of the storage device 2400. At least another of the registers 2840 may be used to manage a value of the lower limit reference temperature of the storage device 2400.

According to an embodiment, at least one of the registers 2840 may be used to determine whether to include temperature information in the command response 2900 to be transmitted to the host 2200. For example, the controller 2800 may include the temperature information in the command response 2900 when “1” is recorded in a relevant register and may not include the temperature information in the command response 2900 when “0” is recorded in a relevant register.

According to an embodiment, the command response 2900 may be bit data (e.g., a bit string). In this case, a bit value (e.g., a first bit value) indicating whether a temperature measured by the sensor 2820 is higher than the upper limit reference temperature may be recorded in a field 2920 of the command response 2900. For example, “1” may be recorded in the field 2920 when a temperature measured by the sensor 2820 is higher than the upper limit reference temperature, and “0” may be recorded in the field 2920 when the temperature measured by the sensor 2820 is not higher than the upper limit reference temperature. Also, a bit value (e.g., a second bit value) indicating whether a temperature measured by the sensor 2820 is lower than the lower limit reference temperature may be recorded in a field 2940 of the command response 2900. For example, “1” may be recorded in the field 2940 when a temperature measured by the sensor 2820 is lower than the lower limit reference temperature, and “0” may be recorded in the field 2940 when the temperature measured by the sensor 2820 is not lower than the lower limit reference temperature.

The thermal throttling operation according to an embodiment may include an operation of adjusting a frequency of a driving clock to be applied to the storage device 2400. The driving clock may be a clock signal needed to drive the storage device 2400, and an internal temperature of the storage device 2400 may decrease as the frequency of the driving clock decreases. Alternatively, an internal temperature of the storage device 2400 may increase as the frequency of the driving clock increases.

Referring to FIG. 6, the host 2200 may transmit a control signal to a clock generator 6000, and the clock generator 6000 that receives the control signal may change the frequency of a driving clock (i.e., controlled clock) to be applied to the storage device 2400. For example, based on the command response (2900) from the storage device 2400 indicative that a temperature measured by the sensor 2820 is higher than the upper limit reference temperature, the host 200 may transmit the control signal to the clock generator 6000 to decrease the frequency of the driving clock to be applied to the storage device 2400. The clock generator 6000 is illustrated as being included in the host 2200, but the clock generator 6000 may be placed at another location in the storage device 2400 or the electronic device 2000.

It should be however understood that the thermal throttling operation may include any operation to be executed by the host 2200 for the purpose of adjusting the internal temperature of the storage device 2400 and is not limited to the above-described embodiments.

In operation S7400, the host 1200 may determine whether there is a need to adjust a temperature of the storage device 1400, based on the temperature information received from the storage device 1400. For example, the host 1200 may determine whether the internal temperature of the storage device 1400 is out of the reference temperature range, with reference to a bit value recorded in a specific field of the command response received from the storage device 1400. If it is determined that the temperature of the storage device 1400 is out of the reference temperature range, in operation S7500, the thermal throttling operation may be performed.

In operation S7500, the host 1200 may perform the thermal throttling operation. For example, the host 1200 may cool the storage device 1400 using a cooler. Alternatively, the host 1200 may adjust the number of commands to be transmitted to the storage device 1400. Alternatively, the host 1200 may adjust a frequency of a driving clock to be applied to the storage device 1400.
